Figure 4. Illustration of pore deformation nanochannels based on SiN and carbon nanotubes. (A) Mechanosensitive SiN nanochannel membranes. The pore size of the membrane changes under the action of pressure. Reproduced with permission^[15]. Copyright 2020, American Chemical Society; (B) The dynamic nano-channel membrane based on CNTs. It can be reversibly switched between the unbent state and the curved state. Reproduced with permission^[14]. Copyright 2019, Wiley-VCH. PDMS: Poly(dimethylsiloxane).
